Definitions

  • the rotator 20 includes a rotatable-side ring plate 21 having an annular shape and acting as a top board, and a generally cylindrical rotatable-side inner circumferential cylindrical section 22 extending downward from an inner circumferential edge of the rotatable-side ring plate 21 .
  • the flat cable C includes the reversed part Cr in the middle of the length direction thereof.
  • the reversed part Cr is a part which is wound in a U shape along one of the rotatable rollers 52 to turn around.
  • the flat cable C is accommodated in the accommodation space S as being wound a plurality of times, but FIG. 3 and FIG. 4 show the flat cable C as being wound once for the sake of simplicity.
  • the openings X each have an arc length which is approximately equivalent to that of each pair of slide guides 25 in the circumferential direction of the cylindrical section 62 .
  • the openings X extend in the axial direction of the cylindrical section 62 and are formed from the vicinity of a top end of the cylindrical section 62 to a bottom end thereof and also to the vicinity of the outer circumferential edge of the bottom ring plate 61 .
  • the openings X are provided in the circumferential direction in an equal number to that of the pairs of slide guides 25 .
  • the brim section 63 includes an inclining section 63 a having a mortar shape inclining obliquely upward and outward in the diametrical direction from a top end of an outer circumferential edge of the cylindrical section 62 , and a brim ring section 63 b extending from an outer circumferential edge of the inclining section 63 a and having an annular shape having an outer diameter which is equivalent to an outer diameter of the leaf spring bearing section 23 .
  • the brim ring section 63 b is generally parallel to the rotatable-side ring plate 21 of the rotator 20 .
